Re: Z axsis assembly issues

I actually have a nut on the other side of the bearing (the makerslide side) so then a plung will push up against the bearing and not into the stepper. I did it for a different reason, I got these metal standoffs for the outside belt mod (which I am totally going to do in the next couple of months) ...

Re: Z axis plastic captive nut.

Thanks for the heads up on oil and the delrin nut. :-) Edit: After reading the comment on delrin swelling when lubricated with oil, I checked the DuPont product literature and it seems its OK (oil resistance) as long the operating temperature is below 60 degrees C. I guess wd40 would come under the...

Re: Z axis plastic captive nut.

I've heard bad things about oil based lubricants near the delrin nut, apparently delrin absorbs oils and swells. I'd go with a dry silicone based lubricant.

*Note As well as dust collects on wet lubricants and gums up your system.

Maybe I will start with nema17 steppers first and then I will upgrade.
I had that problem. I used a tungsten carbide bit to get the last bugger off :-)

Re: Batch 2 Makerslide Frustration

Yesterday I arrived at the same point. Hole distance on makerslide is lower than on the plate. Inventables still handle this issue for europe? If I redrill the plate which hole is better to enlarge? 6.5 is the diameter to go or 6 is enough? By the way I would feel much safer with 16mm bolt, alumini...

Re: ShapeOko Build 616

Great build log! This is the first time I've heard about any noise with the TinyG's acceleration profiles, how is it doing otherwise? I'm keen to upgrade my electronics to a TinyG at some point in the near future. I'm assuming that's part of the noise I'm hearing, kind of sounds like grinding. It m...

Re: ShapeOko Build 616

So, I put the machine together and started doing some test runs. Currently I'm only cutting poster board, which is basically paper sided foam, and its yielding good results. Here are some of the things I've created and cut A Mario coin and stand for my wife, created in Draftsight and cammed in CamBa...

Re: ShapeOko Build 616

Well I finished putting this bad boy together. Still not sure on the belt tightness as it definitely added some resistance to the motion, but it didn't feel too tight (doesn't make a harmonic when strummed). ItsAlive.jpg I did some hello world stuff with not so hot results and Edward recommended add...

Re: ShapeOko Build 616

I finished the X and Y axis XandY.jpg I messed around with V-Wheels and tightness until it went smooth. I then attempted to do the Z axis. This was not fun, I had to cut the holes out a bit to fit the makerslide again, but the biggest issue was that damn nut. I ended up having to take the nut off co...
